Maxuss AA 3000 mah from DX
http://www.dealextreme.com/p/maxuss-1-2v-3000mah-ni-mh-aa-rechargeable-batteries-2-pack-7729
Tested 3 so far. 2 cycles
1. 1750
2. 1731
3. 1800
Maha c 9000
Button top
Length 50 mm
diameter approx 14mm. sorry dont have a digital caliper
Very poor performance against claimed capacity. I wonder if they are re badged 2400 or 2000 or are they equally poor performers.
I have some ready to use Varta aa 2100 and 2500. I will not post results as they are not new and have been "cooked" a few times on the 15 minute charger. I noted that the 2100 has been charging for almost 3 hours and the capacity was 2400 mah and climbing. The battery felt overly hot so I stopped it charging. I'll buy a new pack and test soon.
Arrived today : Matsushima AAA LSD [ 80% after 1 year ]
Capacity claim 750mAh min to 800mAh
Will start these ASAP
Discharged straight from the packet :
Cell 1 / 461mAh
Cell 2/ 0mAh
Cell 3/ 429mAh
Cell 4/ 428mAh
Charged and discharged
Cell1/ 679mAh
Cell2/ 692mAh
Cell3/ 702mAh
Cell4/ 714mAh
Just got a pack of Trustfire grey 16340 protected. I'll try to find a way to asses their capacity to contribute to the list.
Soshine 1100mAh Ni-MH Rechargeable AAA Batteries with Case (4-Battery Pack) from http://www.dealextreme.com/p/26987 ($6 shipped), non LSD
La Crosse BC-900 charger. Brand new cells.
Charger Test mode results: 1022 1007 1035 1050 ma (charge 500 ma, discharge/measure capacity at 200 ma, recharge at 500 ma, cool down)
2nd cycle 500 ma Discharge mode results: 1050 1066 1078 1096
I think these are pretty good numbers for inexpensive AAA cells, and they are nicely consistent across the 4 cells. They also get good reviews on DX. They arrived almost 100% discharged.
Some Pisen AAA's arrived a short while ago , also some 18650's [ Sanyo - Samsung ]

Well , look nothing like the picture .. 800mAh capacity claim , Pre charged claim , and low self discharge claim , Since its in Chinese ???
Will discharge first , then charge and re-discharge from being fully charged .
Out of the Packet : Discharged @ 500mAh
1/ 680mAh
2/ 688mAh
Ok charged them up , and then discharged again at 0.5A
1/ 793mAh
2/ 804mAh
Those are pretty decent numbers but who knows how they'll hold up over time.
Just got this one in , Sanyo 2600mAh capacity .. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=370406814898&ssPageName=STRK:MEWNX:IT#ht_2220wt_905
Discharged at 0.5A to 3v .. Now some manufacturers say you can discharge to 2.75 or 2.5 Volts under load ..
Anyhow , the hobby charger stops at 3v under load = 2433mAh to 3v ..
Being Sanyo there is no protection circuit ..
Discharge Termination Voltage: 2.75V
Capacity: 2800mAh (Min 2750mAh)
Well , after charging to 4.2v , and then discharging to 3v under load [ 0.5A ] I got some 2486mAh ...
If I were able to discharge lower it may have come close [ may have ] to the claimed minimum .
So keep in mind that discharge is between 4.2v and 3v ..
Thanks again for all the work you're doing collecting data on these batteries, Old4570!
Unfortunately more Junk ...
Discharged as arrived = 0 capacity
Charge @ 0.5A then discharged @ 0.5A
= 1st cell was 251mAh / 2nd cell was 263mAh , which is really poor capacity ...
Pic in the bestinone thread.
Claimed capacity 600mAh - first one tested gave 568mAh on a Turnigy Accucell 6 at 500mA discharge rate. Semi-button top.
Hold output on a demanding AA (It does have an XM-L in it) light better than a flame Trustfire - both freshly charged, the IMR on its first cycle, the Trustfire with less than 5 charges.
Replentished my supply of Eneloops from www.hkequipment.net last week. 8 AAs for $29.99. (ordered on 17/2 arrived 4/3 in Aus)

I am running a break-in cycle on the other 4.
(I love these batteries)

I think I love my eneloops more than my flashlights. I have 100 (72 aa & 28 aaa) and I'm still thinking about getting more. I think my next set of eneloops will be those glitter ones since I already have the white, costco, tones, and XX eneloops. I have so many that I don't get to use them but I do maintenance on them with my C9000's. It's just as fun to me. :bigsmile:
You just gotta love them eneloops.
Semi-button top - the button protrudes about 0.1mm from the top of the cell.
Unprotected
Diameter 14.2mm, length 49.9mm. For comparison, an Eneloop with my calipers measures 50.1mm length and 14.3mm diameter. Both lengths include the button.
Capacity at 1A discharge to 3V (Turnigy Accucell 6) - 558mAh. Will try the other three to get average numbers over four of them.
Second Bestinone IMR 14500
Discharge 1A - 559mAh
Third one
Discharge 1A - 566mAh
Well, I have been inspired by you guys and finally got the Turnigy Accucell 6 in the mail.
First test was a Hi-Max 18650 Protected 2600mAh from ebay
Claimed capacity = 2600mAh
Discharge @1A = 2481mAh
68.8mm x 18.2mm

Turnigy Accucell 6 Charger
Happy with this cell, and will probably get the 6 piece that the seller offers next time. The going counter offer is $34 shipped now?
Last of my Ebay AAA purchase has arived ...
Discharged as they arived :
1/ 53mAh
2/ 41mAh
Charged at 0.5A and then discharged @ 0.5A
1/ 177mAh
2/ 210mAh
What can I say , thats bad , real bad .. Hopefully this will give anyone reading these posts some idea of what there getting when they buy the cheap chinese cells .
I bought some new batteries today
Brand: Woolworths Essentials
AAA 800 mah 4 pack
Price $13.98
These come with a 100 % money back guarantee (which I feel I will be claiming soon)
Initial discharge results at 500 ma.
1. 0
2. 4
3. 2
4.0
These were discharged and showing less than 1 volt.
I am currently charging and then will discharge but I am not expecting good results. They are made in China and it does say they should be charged before use.
Hmm I may be proven wrong
Charged at 500 mah
1. 1.44v 883 mah
2. 1.46v 1061 mah *
3. 1.46v 1091 mah *
4. 1.46v 1196 mah *
* They sat on 1.46 volt for a long time and kept taking charge??
I may see good discharge results. However they are NOT LSD and in real use would be poor I imagine.
results
1. 785 mah
2. 794
3. 814
4. 822
on maha c 9000
Quite good but for the price I'd rather have eneloops. Will recharge and leave for a week and then discharge.
